We report on our studies of the light shift in a miniature atomic clock based on Coherent Population Trapping (CPT) in Cesium. There is no data published in the literature on the frequency and intensity-related light shift coefficients for CPT atomic clock on the Cesium D1 line, only for the D2 line. With our data we fill this gap and report on the measurements of light shift for the Cs D1 line in...
We report on the microfabrication and packaging of Cs-vapor cells filled with Ne or Ar for micro atomic clocks (MACs) based on the coherent population trapping (CPT). We present a two-step anodic bonding process to control the cell atmosphere for long-term operation of MACs. Furthermore, the results of thermal analysis of a cell embedded in the physical package are shown in order to discuss the optimal...
Presented is the observation of a quadratic temperature dependence of the Cs 0-0 ground state hyperfine resonance frequency in a single Neon (Ne) buffer gas vapour microcell. The inversion temperature, expected to be theoretically independent of the buffer gas pressure, is measured to be about 80-C for two different samples. A proposal to develop chip scale atomic clocks with improved long-term frequency...
This paper presents the preliminary results of developments of the European version of MEMS atomic clock presenting a short-term stability of 5times10-11 over 1 hour while operating with less than 200 mW power consumption. The frame of such developments is the European proposal MAC-TFC (www.mac-tfc.eu), bringing together a consortium made of five major academic institutions (University of Besanccedilon,...
Cesium vapor microcells incorporating a Cs dispenser were fabricated. An organosilane monolayer was successfully applied to the microcell walls as an anti-relaxation coating to improve the relaxation time of Cs atoms.
